JAMES M. EVANS, OF SPRING VALLEY, NEW YORK.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 429,431, dated June 3, 1890.

Application filed November 2, 1889- Serial No. 329,070. (No model.)

To all whom it may concern.-

Be it known that 1, JAMES M. EVANS, of Spring Valley, in the county of Rockland and State of New York, have invented a new and useful Improvement in Lubricators; and I do hereby declare that the followingis a full, clear, and exact description of the same.

The object of the invention is to provide removable oil-chambers and to prevent the stoppage in the flow of oil while the supply is being renewed or the water of condensation removed; and my invention consists in combining in a lubricator two or more removable oil-chambers with a suitable cut-olf valve, by which one oil-chamber may be removed for refilling and cleaning while the flow of oil is kept continuous by bringing into action'the second oil-chamber.

In the drawings, Figure 1 is a side elevation of the lubricator with the connections therefrom. Fig. 2 is a sectional view on line a 00 of Fig. 1. Fig. 3 is a detail sectional view of the valve.

In the drawings, the steam-pipe A and the condenser O,with pipe-connections 1 2 thereto, may be of any well-known form, an ordinary angle-valve 3 being also employed. The condenser O is formed with or secured to a valvecasing 01 at its lower end, and from the end of this casing extends the oil-pipe 4', which connects with a sight-feed tube 2', through which the oil passes upward, and to the steampipe through the connection 5, though it will be understood that the tube may be arranged so that the drops of oil Will fall instead of rising. This valve-casing is formed with two screw-threaded. nipples is, arranged in the present instance divergent from each other, and to each of these is screwed an oil-chamber f, which is preferably in the form of the dependent bulb shown, and may be made of glass or metal, as desired. The valve extends longitudinally through the casing and is provided with a transverse port 6 and a threeway port 7. The former communicates with the condenser at one end and through an opening 10 in the casing with the oil-chamber at the other end, so that when the valve is properly adjusted the water of condensation will pass from the condenser through the valve into the oil-chamber. The displaced oil passes through the opening 11 in the valve-casing, the three-way port 7, and thence through the sight-feed tube to the engine. By means of the valve, communication with either oil-chamber may be cut off, and this may be removed for filling or cleaning, while the continuity of the flow is preserved by bringing the second chamber into communication with the condenser and steam-pipe.

I do not wish to limit myself to the precise form of valve shown, as it is obvious that the valve portion of the device may be arranged .-in other Ways.

Within each oil-chamber is a removable conduit-pipe e for the water of condensation. The upper end is beveled to fit the opening 10, and at its lower end is secured a spring which bears upon the inner wall of the chamber and by its pressure keeps the pipe in place. About the upper end or mouth of the bulb is a lip Z, which will catch any oil or water that may ooze from the joint here.

It will be understood that one principle of my invention may be embodied in a form of lubricator in which the oil-chambers are not removable, the'valve mechanism being combined, as above described, to cut off communication with either chamber while the other is being cleaned or drained of the water of condensation.

. I claim as my invent-ion 1. In combination, in alubricator, condensing means, an oil-chamber, a second oilchamber, and valve mechanism for controlling communication between the condenser and'the oil-chambers and between said chambers and the steam-pipe, substantially as described.

2. In combinatiomin a lubricator, condensing means, an oil-chamber, a second oilchamber, both of said chambers being removable, and valve mechanism operating between the condenser and said chambers, whereby communication between the condenser and one chamber may be cut off to permit the removal of said chamber, substantially as described.

3. In combination, in a lubricator, condensing means, a valve-casing and valve, an oilchamber, and a removable conduit-pipe within the same, having a spring at its lower end bearing upon the interior of the ehamber,j In testimony whereof I have signed my substantially as described. name to'this specification in the presence 01:
